Low height, small footprint, light weight. 2 Description Antenna for reception of GPS signals (1575MHz). SMD antenna. Uses matching circuit and cut-out area for optimising efficiency. Product Specification The antenna has balanced antenna characteristics. The minimum populated ground plane size is 20 x 30 mm (LxW) The antenna has RHCP characteristics suitable for reception of GPS signals. The antenna patterns are given in section 7-2 Radiation Patterns. It should be noted that the radiation patterns change with the size of the ground plane as described for the two reference boards indicated in section 7-2 Radiation Patterns. 3 Application Antenna for mobile phones and handheld devices with embedded GPS systems Application specific tracking modules Mapping software accessories: USB dongle, SDIO cards, PCMCIA card.

For more details please contact Antenova Technical Support. The antenna is mounted on the PCB using soldering pads. The antenna is connected via one feed, four ground pads and two isolated pads. A cut-out is required in the PCB as detailed. 7

8 10 General Application Guidelines GPS RADIONOVA Co-planar Antenna Placement of the antenna. The antenna shall be placed on an area with the PCB cut out (see drawing on page 7), preferably at the edge of the PCB. Placement of GPS radio module. To avoid losses in the strip line, the module shall be placed as close to the antenna as possible. Matching Circuit The antenna requires a matching circuit, a PI network is recommended. This should be placed as close to the antenna feed as possible. Component values are depending on antenna placement, PCB dimensions and location of other components. Vias should connect all ground layers. Vias should be used to fence in the feed track from the radio to the antenna. Vias should also be placed close to the ground pads of matching components. Vias size and spacing depends on the application but generally 0.3 to 0.5mm diameter, spacing 3 to 10mm. Strip line. The strip line must be dimensioned according to your specific PCB. No crossing strip lines are allowed between the strip line and its ground plane. Via connections. To avoid spurious effects, via connections must be made to analogue ground. Clearance. Minimum clearance to other components is 2-5 mm. Casing material. No metal casing or plastics using metal flakes shall be used, avoid also metallic based paint or laquer. Note! Incorrect implementation of the antenna will affect the performance. Contact Antenova for implementation services and technical support. 11 Lead Free Soldering The antenna has been tested and approved for lead free soldering. (See 12.4). Follow the guidelines and reflow temperature vs time data for the solder paste supplied by the solder manufacturer. 12 Test Standards Conformance (Information provided in this section is based on similarity and analysis with Antenova s existing products.
